Outcomes
Primary Outcome Measures
Patient satisfaction measured using the Patient Global assessment of Medication Performance (GMP)at the time of discharge
Global assessment of Medication,which is an assessment, performed by the patient, of the patient's impression of how well the medication works. The patient is asked to rate the pain relief given by methoxyflurane using a 5-point likert scale - 0=poor;1=fair;2=good;3=very good;4=excellent
Secondary Outcome Measures
The Overall/Maximum pain intensity experienced at any point during the procedure using a numeric rating scale
Patient is asked to rate the intensity of the pain experienced using an 11-point numeric rating scale is used. A score of 0=no pain and a score of 10= worst pain possible
Percent patients requiring rescue medication
Documentation of the use of rescue medication post administration of methooxyflurane Documenting first time of use of rescue medication, type of medication administered,dose and route
Safety outcome measure to assess percentage of patients requiring rescue medication
Documentation of adverse events as safety outcome measure by the health care professional
Health professional impression of how well the medication worked measured using the Patient Global assessment of Medication Performance (GMP)at the time of discharge
Global assessment of Medication Performance, is an assessment, performed by the health care professional, of their impression of how well the medication works. The health care professional is asked a single question "rate the pain relief provided by methoxyflurane using a 5-point likert scale - 0=poor;1=fair;2=good;3=very good;4=excellent
Assessment of how well the medication fulfilled the patient's expectations of pain relief using the Fulfillment of of Pain Relief Expectation Scale
The patient is asked a single question "To what extent has your expectations regarding pain control been met?", using the Fulfillment of Pain Relief Expectation scale, which uses a 5-point Likert scale - 0=poor;1=fair;2=good;3=very good;4=excellent

5. Study Description
Brief Summary
The participant will be trained to self administer the drug and will be supplied with a PENTHROX commercial inhaler kit .The study nurse will train the participant and supervise its use during the procedure.Immediately following the procedure the participant will be asked to fill out two brief questionnaires. The study nurse will assess the participant for adverse event and will follow-up with a phone call 24 hours later.
Detailed Description
Many patients with chronic urological conditions require multiple and sometimes painful urological procedures. Ideally these procedures may be done in the cystoscopy suite without a general anesthetic. Low dose methoxyflurane, (MEOF)is a inhaled, self-administered non-opioid analgesic and has been approved by Health Canada's for the short-term relief of moderate to severe acute pain, associated with trauma or international medical procedures, in conscious adult patients. The brand name is PENTHROX.
This study is a single centre, pilot study to assess the feasibility of using a self-administrated, MEOF for pain relief during minor out-patient urological procedures. Eligible participants will receive a one time dose of the the study medication during a planned, outpatient urological procedure done under cystoscopy in the Cystoscopy clinic

Intervention Description
As soon as possible following enrollment and initial procedures, the patient will be supplied with a PENTHROX™ kit which includes one inhaler containing 3 mL of MEOF for pain management. A member of the research team will train the patient to self-administer MEOF. PENTHROX™ is an approved (trademarked) product in Canada and is commercially available in a combination blister pack with one 3 mL sealed bottle and one PENTHROX™ inhaler with the Activated Carbon (AC) chamber.
